BATH-TUB.

Specification of Letters I Patent. Pang-need June 21, 1916..

1 Application filed January 12, 1910. Serial No. 537,588.

To all whom it'may concern:

Be it known that I, JosErH H. NEAL, a citizen of the United States,residingat Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Bath-Tubs, ofwhich the following is aspecification.

This invention relates to cast-metal bathtubs.

One object of my invention is to provide bath tubs with an improvedtop-roll having therein a water-conduit that shallbe formed in thefoundry operations of molding and casting, by the use of a sand-corethesaid water-conduit to have such novel structural features as will enablethe said sand-core to be readily broken up and removed after the castingoperations have been completed.-

Another object of the invention is to rovide a bath-tub with a top-rollwater-con uit which will receive its supply of water at the front end ofthe tub-and said conduit to have such featuresv that the water will flowthrough the conduit from the said point of supply along both sides ofthe top-roll without dlscharging, until it has passed the median linebetween the front and rear ends of the tub, and then such water while itcontinues to flow after passing said median line shall freely dischargefrom the conduit and run down the inner surface of the wall at the rearpart of the sides and at the end of the tub.

Another object of the invention is to provide a cast-metal bath-tub witha seat formed at one end of the tub and of metal integral with the tubstructure, and also to provide the top-roll ofthe tub with awater-conduit that shall discharge water into the tub only at that partwhich is at the sides or around the said seat.

Another object of the invention is to provide a bath-tub with a top-rollwater-conduit and to also provide the tub at its front end with awater-receiving chamber which shall be in communication with saidwaterconduit, whereby the water supply coming from the pipes underressure will first enter the said chamber w ere the force of the waterwill be broken, and then flow from the chamber into the said conduit.

The invention is illustrated in the accompanying drawing in which,

. Figure 1 is a perspective side and top view of the improved bath-tub.Fig. 2 shows on a larger scale, a vertical cross-secto flow, but willalso tion taken on the line 22, of Fig. 1, showing the top-roll and thewater-receiving chamber. Fig. 3 shows a cross-section of the top-rolland water-conduit, taken on the line 33. Fig. 4 shows a similar sectiontaken on the line H, over the seat.

In making porcelain enameled bath-tubs, the tub is first made ofcast-iron in the foundry and is then enameled. Tubs of the class towhich this invention relates are made and enameled as just mentioned.

In this invention the top-roll, C, is of special formation in order toproduce a waterconduit, 6, havin the desired structural features. Thebat -tub, A, the conduit, 6, and the roll, C, are all integralcast-iron. In molding the top-roll at the foundry to form the conduit,1), a sand-core is used and in order to provide for the removal of thesand-core a slot, 03, is formed along the inward side of the roll, C,and at the top of the wall, 6, of the bath-tub. This open slot extendsentirely around the top of the bath-tub except at the front end. It willbe seen by reference to Figs. 1, 3 and A of the drawin that in formingthe slot the contour an shape of the upper surface of the top-roll ispreserved or may be shaped as preferred and the efiect of the slot, 05,is to produce on the top roll a lip, 7, that projects toward theinterior of the tub, but stops short of a vertical line coincident withthe inner surface of the tub-walls. For one half of the length of theconduit said lip is directly over a raised edge, g, shown in Fig. 3, atthe top of the bath-tub wall, e. The top-roll thus made serves all thepurposes and advantages which is served by the ordinary top-roll used onother tubs, and in addition this improved roll with its conduit, 6, andopen-slot, at, will permit of the sand-core belng readily removed, willallow the porcelain enamel to be a plied within and will also providefor the ow of water in the conduit as 'far along as said raised edge, g,extends which is from the front end to a little past a vertical medianline, indicated by the letter, 00. From the point indicated to the rearend of the tub the conduit is without the raised edge, 9, and the shapeof the edge at this part 1s like that shown at, h, in Fig. 4. B'y-thisconstruction the water after flowing ast the raised edge, 9, at oint,:23, will continue eely discharge along the lower edge, h, of theconduit and run down the inner surface of the wall, e, at the rear partof the sides and at the rear end.

In the vertical direction the tub is deeper at the front end than at therear end, as seen in Fig. 1. The deepest part of the tub is at thelowermost horizontal bottom line, i; this dee est part has a rearvertical wall, k, which is in vertical alinement with the median linejust forward of said point, :0. The shallow part of the tub is at theuppermost horizontal bottom line, y. This construction forms inside ofthe tub a seat which is indicated just above the line, j. The so-calledseat will be of cast metal integral with the tub structure and comprisesthe entire high part of the tub-bottom at the rear end. The relativeposition of this seat with respect to that part of the water-conduitthat has the low edge, h, is such that the water will discharge from theconduit and flow down the side and end walls, 0, around said seat. Byusing hot water the walls and seat will be made warm. A person can siton the seat above high part, 9', and place his feet in the deeper partat '21.

A pedestal or standard, Z, is under the rear end of the tub and supportsthe same.

At its front end the tub has a water-receiving chamber, m, formedintegral with the front-end wall, 6, of the tub; this chamber isconstructed with its lower end open in order to remove the sand-corethat must be used in molding the chamber. A plate, a, closes said lowerend.

A surface, C, same as the top-roll covers theupper end of thewater-receiving chamber and below this top surface said chamber has atopposite sides, a suitable opening, p, see Fig. 2, and said openingscommunicate with the water-conduit, b. The pipe or pipes, g, which leadfrom the watersupply, enter the said water-receiving chamber. The waterfrom these pipes, g, is usually under considerable pressure, and as thewater must first enter the chamber, m, the force of the water will bebroken'or lessened, and then with a reduced pressure the water will flowfrom the chamber, m, into the conduit, b, of the bathtub. The waste ordischarge of water from the tub takes place through pipe, 1'.

Bath tubs of cast-metal are usually if not always coated with vitreousenamel, and therefore the structural features of this tub have all beendesigned with reference to the practicability of the parts beingenameled.

Having thus described my inventionwhat I eulaim and desire to secure byLetters Paten 1s,

1. A cast-iron bath-tub having a 110110 top-roll that contains awater-conduit which has directly over the wall of the tub an edge, 9,higher than the bottom of said conduit said higher edge confining thewater to the conduit and extending from the 'front end of the tub to amedian line between the said front and rear ends, and which conduit fromsaid median line and extending to the rear end of the tub has a lowedge, h, which permits the Water in the conduit to run down the innersurface of the tub-wall. I

2. A cast-metal bath-tub whose bottom is divided into two distinctparts-the frontend part being in a lower horizontal plane than therear-end part which latter being higher serves as a seat, incombinationwith a hollow top-roll that contains a water-conduit providedwith an open slot along the inward side of the roll-said conduit havinga raised edge, 9, which confines the water to the conduit and extendsfrom the front-end of the tub back to a point above the front of saidseat, the conduit from said seat back to the rear-end of the tub havinga low edge, it, which permits the water to'flow from the conduit downthe sides of the wallsaround and onto the seat.

3. A cast-metal bath-tub provided wlth a seat at the rear-end of thetub-said seat b'eing integral with the metal of the tub, and alsoprovided with a top-roll water-conduit which receives the water-supplyat the front I JOSEPH H. NEAL.
